3 Claims. 1

My invention relates to 'multi-switch means and has particular relation to mum-filament lamp switches.

Switch means for multi-filament lamps .in present use require a number .of .push button or rotating switch operations 'to change :from one filament or combination of :fil'aments to another, as well as requiringseparate cut-out switch-operations to .turn off the various vlight filaments. I have devised a zmultl-filament lamp switch wherein the operation .of-each-pushbutton will turn on one of a number of filaments or combination of filaments on the multi-iilament lamp, and at the same time willturn offany filament or combination of filaments already on.

An important object of my inventionis 'to'provide multi-filament lamp such as a "fl'oor'lamp which is provided with switch means having a number of push buttons, each one of which controls a switch means to turn'ofi a filamentora combination of filaments in the multi-ifilament .multi-filament lamp switch means wherein the said multi-push button means, when actuated, will turn ofi any filament 'or combination of'filaments already lighted up in the multi-r'filament lamp.

A still further object of my invention is to provide multi-filament lamp means having .a multi-filament lamp bulb 'of a type such as the mogul lamp bulb, together with a number or" single filament lamp bulbs, all electriceillyconnected to the above mentioned multie'filament lamp switch means.

A still further object of my invention is .to provide lamp cord and plug means attachable to any standard electrical outlet.

A still further object of myinventionis to, pro vide multi-filament lamp switch .means wherein any plurality of thepush-buttoncontrols maybe actuated at the same time to turn on-andlightnup all of the filaments connected to the .multi-filament lamp.

A further object of my invention is to tprovide a push-button control connected with-my .multifilament lamp switch which will turn off .any or all of the light filament previously turned .on.

A still further object of.my invention'is to1pr0- vide a modification to the :wiring and :s-Witch .mechanism .of .my multi-filament switch .means invention will be :disclosed in .the following description and .in .the accompanying illustrations in which like ,parts are designated by like numerals, and in which;

.Fig. .1 is van elevation view .of my invention showing its component parts together with a "lamp. shade drawnin phantom lines.

:Fig. 2 is an enlarged fragmentary viewof my invention with parts cut away to show its interior construction.

.Fig. 3 .is .an enlarged cross-sectional view of the switch means of my invention .taken substantially online 33 on Fig.2.

.Fig. .4 is across-sectional view .of the switch means of :my invention taken substantially on lined-4 on Fig. 3.

Fig. 5 is an enlarged perspective view of -;one of the 'switch means comprising apart of my in- 'vention.

Fig. 6 is an electrical Wiring diagram of .myin- "vention.

generally designated .8 and consists of a floor lamp 9 having-a lamp base 55, candelabra 30, a

reflector 33,, lamp-cord .and plug means 35, 'and 'a-lampshadeiitd.

Switch .housingmeans 10 is attached'at a .con-

'venient place just below the .icandelabra 30 on the floor-lamp '9 'and 'has formed on its surface :a number :of :switch button receptacles I l formed preferably ain radially spaced arrangement. The saidzswitch housing .means [0 may be of a square tor rectangular shape with :rounded corners as shown and :made of an :insulating ':material such :plastic.

Multiple switch ."button means I2 are located,

-one within each of the .switchbutton receptacles -l-l ofwhich sevenxare shown in'the illustration.

Switchfshank means 1.3 are secured .to the said multiple switch button means :12 and are posiitione'd and 'heldsin-placeby shank retaining slots l4, radially positioned in a shank retaining disc I5, which is secured to the underside of the top of housing It.

A switch actuating disc i6 is rotatably mounted at IT on a trunnion i8 within the housing in, on the switch base [9. Arcuate cut out means 28 on switch actuating disc 16 are formed in alignment with the switch shank means it! to allow the said switch shank means to pass therethrough and contact by means of contact actuators 2b, a number of electrical contact means 2i located on base it as shown in Fig.3.

Multiple switch setting dogs 2i are mounted on the top surface of the switch actuating disc l6 as shown in Figs. 3, 4, and 5, and are provided with cam surfaces 22 and switch catch means 23. Cam engaging slots 25 are formed in each of the switch shank means It to engage the said cam surfaces 22. Catch engaging slots 24 are formed above the said cam engaging slots in the switch shank means l3 to engage the switch catch means 23 when one of the push buttons i2 is depressed.

A coil spring 29 is located on trunnion l8 and one end is secured to said trunnion l8 and the other end to the switch actuating disc it to urge the said switch actuating disc it in a clockwise direction as shown by arrows in Fig. a. Tension springs 23 are secured between contact actuators 2G and switch actuating disc it to urge the push buttons l2 to a normal upraised position.

To operate the light switch means 8 a button 52 is depressed as shown in solid and dotted lines in Figs. 3 and 5. Cam engaging slot 25 rides on cam surface 22 on dog 2i, causing switch actuating disc it to rotate in counterclockwise direction and allowing the catch means 23 on dog 2! to engage the catch engaging slot t l holding the contact actuator 28 against the contact means 21 and thus closing the electric circuit. If the button it or any other button 92 is depressed thereafter, the dog 2| will be disengaged from slot M allowing the button iii to spring up and break the circuit.

In the illustrations and a multi-filament lamp bulb 32, having a one hundred and a two hundred watt filament, is used, and three sixty watt single filament lamps are used. Using lamp bulbs oi the above described wattage it is possible to obtain fifteen light watt combinations ranging from sixty watts through four hundred and eighty watts.

In the wiring diagram of my multi-filament lamp switch means, as ilustrated in 6, a switch button designated 39, when depressed, ac tuates or closes contact 2?, causing filaments 5i and 52 of the mogul lamp 32 to ligh up by means of connecting wires ll] and ll and lead and return wires 3'! and 33 to the source of power 35.

The push button designated 52, when depressed, turns oil any filament already lighted and in urn turns on or lights up the filament designated 5! in lamp 32. The push button designated 53 turns off any previously turned on fila ment and through wire 5'] lights up the filament E2 in bulb 32. The push button depressed, turns oil any previously turned on filament and in turn lights up the single filament lamp bulb 8!, Ma and 3w by means of its double switch as shown. Push button when depressed, turns off any previously lighted filament ant. in turn lights up the two single filament bulbs 3m and 3H). Push button it, when depressed, turns off any previously lighted filament and through wire 58 lights the single filament bulb 35. The cut 4 out switch 49 will cut out or turn off any or all lights that are lighted by means of the above described switch cut out means as shown by dotted line in the diagram and designated 55.

It has thus been brought out that any one of the push buttons l2 when depressed, will light up any filament or combination of filament that it controls in the multi-filament lamp means an will also turn ofi any filament or combination of filaments previously turned on. It is also possible to depress two or more of the push buttons i2 at the same time and light up any combination of filament in the lamp, or all of them at one time and with one operation.

I believe that the above described switching operations are novel and a distinct improvement over multi-filament lamps in present so in which a number of switching operations are required to turn ofi or turn on the various filaments and com bination of filaments.

Fig. '7 is a modification of the wiring diagram shown in Fig, 6 wherein the number of switch-- ing operations and mechanica1 parts are reducer by making use of bifurcated switch means and "a l to do away with four of the switches used in the illustrated switch means in Figs. 3 and l and in wiring diagram 5. The filament wi in switching sequence remains substant the same in diagram I as that illustrated an described for diagram 6.

Although my invention has been described, the terms used are to be deemed terms of description rather than terms of limitation, my invention being to retain the right to all mechanical equivalents of the structural elements depictec, provided they fall within the purview of the aupended claims. 7

' Having thus disclosed and revealed m inventron, what I claim as new and desire to secure by Letters Patent is:

1. In a lamp structure, a plurality of in descent filaments connected in a parallel circ and a plurality of push button switch ele; ants, the total number of push button switch elements consisting of one push button switch element for each different circuit desired plus one button switch element for opening any circuits that may be closed, connected in said parallel oirc in such a manner that any one of the filamei may be energized by depressing a correspondi push button element, and any combination of filaments may be energized by depressing another corresponding push button element.
